Color's Attention War
Why do flags and art use such bold colors?

Stand in a crowded square and look around. A hundred different jackets, a thousand faces, signs everywhere — and yet your eyes snap straight to the flag rippling overhead. Why? What makes those bright blocks of color punch through all that visual noise?
Your eye is a competition arena. Everything you look at is fighting for your attention — the tree, the car, the person walking by, the sky. Your brain can only focus on a few things at once, so it has to pick winners fast. Bold colors are the loudest contestants. They basically shout "LOOK AT ME!" while soft colors whisper.
